Death of David Neligan, Intelligence Agent & Police Detective

David Neligan, intelligence agent, police detective and superintendent known by his sobriquet “The Spy in the Castle,” dies on October 6, 1983, at St. Vincent’s Hospital in Dublin. He is a figure involved in the Irish War of Independence (1919–21) and subsequently becomes Director of Military Intelligence for the Irish Army after the Irish Civil War (1922–23).

Neligan is born on October 14, 1899, at Templeglantine, County Limerick, where his parents, David and Elizabeth Neligan (née Mullan), are primary school teachers. He is an accomplished hurler with his local Templeglantine GAA club. In 1917, he joins the Irish Volunteers, the military organisation established in 1913 by Irish nationalists.

Against his father’s wishes, Neligan joins the Dublin Metropolitan Police (DMP) – also in 1917. Picking up travel documentation from the local Royal Irish Constabulary barracks, he declines a suggestion that he enlist in this armed rural force. After service as a uniformed constable with the DMP, he is promoted to Detective and transferred into the Department’s widely hated counterintelligence and anti-political-subversion unit, the G Division, in 1919. In May 1920, his elder brother Maurice (1895–1920), an Irish Republican Army (IRA) member and friend of Michael Collins, persuades him to resign from the DMP.

After his resignation, Neligan returns to his native County Limerick with the intention of joining the Limerick IRA. Shortly afterward, Maurice is killed in a motorcycle accident, near their home in Templeglantine. In the meantime, Neligan also receives word from a family friend that Michael Collins wishes to meet with him in Dublin. Collins is outraged that Neligan has been allowed to resign and persuades him to rejoin the DMP as a mole for the intelligence wing of the IRA. Along with Detectives Eamon Broy and James McNamara, Neligan acts as a highly valuable agent for Collins and passes on reams of vital information. He leaks documents about the relative importance of police and military personnel and also warns insurgents of upcoming raids and ambushes. There are unconfirmed rumors that Neligan might be a double agent working for British interests.

In 1921, Collins orders Neligan to let himself be recruited into MI5 and he uses the opportunity to memorise their passwords and the identities of their agents. All of this is passed on to Collins. After Broy and McNamara are dismissed in 1921, Neligan becomes Collins’ most important mole inside Dublin Castle.

On the outbreak of the Irish Civil War in June 1922, Neligan joins the Irish Army in Islandbridge Barracks with the rank of Commandant, and is attached to the Dublin Guard. He is involved in the seaborne assault on Fenit, County Kerry, and spends the remainder of the war serving as a military intelligence officer operating between Ballymullen Barracks, Tralee and Killarney. He is involved in atrocities alongside Paddy Daly including the Ballyseedy massacre, mock executions and the torture of prisoners using crowbars and is sometimes referred to as the “Butcher of Kerry.” In 1923, he is posted to Dublin, where he is promoted to Colonel and succeeds Diarmuid O’Hegarty as the Irish Army’s Director of Military Intelligence.

In 1924, Neligan hands over his post to the youthful Colonel Michael Joe Costello and takes command of the DMP, which still continues as a force separate from the newly established Garda Síochána, with the rank of Chief Superintendent. The next year he transfers to the Garda when the two police forces are amalgamated, and is instrumental in the foundation of the Garda Special Branch. When Éamon de Valera becomes head of government in 1932, his republican followers demand Neligan’s dismissal. Instead, Neligan is transferred to an equivalent post in the Irish Civil Service. In June 1935, he is married to fellow civil servant Sheila Maeve Rogan. They have one son and three daughters, and reside at 15 St. Helen’s Road, Booterstown, Dublin.

Neligan draws pensions from the DMP, the British MI5, the Garda Síochána and the Irish Civil Service. He also receives an “Old IRA” pension through the Department of Defence.

Birth of Florence O’Donoghue, Historian & IRA Member

Florence O’Donoghue, historian and head of intelligence of the Cork No. 1 Brigade of the Irish Republican Army (IRA) during the Irish War of Independence, is born in Rathmore, County Kerry, on July 22, 1894, the son of farmer Patrick O’Donoghue and Margaret Cronin. He moves to Cork in 1910, where he works as an apprentice in the drapery trade.

The 1916 Easter Rising is a watershed in O’Donoghue’s life. In December 1916, he joins the Cork branch of the Irish Volunteers. In early 1917, he is elected unanimously First Lieutenant of the Cyclist Company and as a result devotes all his spare time to Volunteer work. He begins writing weekly for two years for The Irish World newspaper. By May 1917, he is sworn into the Irish Republican Brotherhood (IRB) and in October, Tomás Mac Curtain appoints him head of communications of the Cork Brigade. He replaces Pat Higgins as Brigade Adjutant in February 1917. He is a key organiser in the sensational jailbreak of Captain Donnchadh Mac Niallghuis on Armistice Day 1918 and takes personal responsibility for his protection. Michael Collins is the last officer from Volunteers General Headquarters to visit Cork shortly after Christmas 1919, until the truce in 1921.

O’Donoghue builds up an intelligence network and agents which includes his future wife, Josephine Marchment. She is head female clerk at the 6th Division Headquarters at Victoria Barracks, Cork, and passes on secret British Army correspondence to him. He recruits people to open letters, tap phone lines and intercept telegrams. The Irish Republican Army has 2,000 active members in Cork which are also used for intelligence gathering. By March 1920, after killing a Royal Irish Constabulary (RIC) Inspector, he is on the run and serving full-time in the IRA. In November of that year, the Cork Brigade kills six British Army officers and executes five Cork civilians on suspicion of spying.

After two and a half years of fighting, a truce is agreed upon on July 11, 1921. When the Dáil approves the Anglo-Irish Treaty, in January 1922, the IRA splits into pro- and anti-Treaty camps. Over the coming months and after being elected to the army’s executive as Adjutant General, O’Donoghue warns of the dangers of an Irish Civil War. In June 1922, he resigns from the army’s national executive and a month later, on July 3, 1922, from the army. Civil war does break out on June 28, 1922, between pro- and anti-Treaty factions, much to his dismay.

During the Irish Civil War, O’Donoghue remains neutral and tries to organise a truce to end the fighting. In December 1922, he forms a group called the “Neutral IRA”, along with Seán O’Hegarty, composed of pro-truce IRA men. He claims he has 20,000 members in this group. He campaigns for a month’s truce between the two sides, so that a political compromise could be reached. However, his efforts come to nothing and in March 1923, he winds up the “Neutral IRA,” judging that its objectives cannot be achieved. The Irish Civil War ends on May 24, 1923.

O’Donoghue serves as major in the Irish Army from 1939-1946. He forms a Supplementary Intelligence Service that is to remain behind enemy lines in the event of an invasion. He also teaches guerrilla warfare tactics to new army recruits.

O’Donoghue marries Josephine Brown (née Marchment) in April 1921, and they have four children. The couple also adopts two children from Josephine’s first marriage, including Reggie Brown, whom O’Donoghue kidnaps from his grandparents in Wales in 1920. He becomes a rate collector and remains outside politics.

In later years O’Donoghue becomes a respected historian. While in the army he edits An Cosantóir, the Irish Army’s magazine. He convinces Éamon de Valera to establish the Bureau of Military History to record personal accounts from the Irish War of Independence. He is a recording officer until 1948. His most famous work is his biography on Liam Lynch, entitled No Other Law.

O’Donoghue dies on December 18, 1967, in Mercy University Hospital, Cork, County Cork. Tom Barry gives the graveside oration. His papers are in the National Library of Ireland (NLI) and his statement to the Bureau of Military History is in the Military Archives.
